Also Steve, a scan of a pre-CAD designed full size car, would only give the data of the "skin" then the real model kit design starts.
The fun thing, IMHO is that, when taking a whole generation of let's say the Jo-Han 1968-70 GTX/Roadrunner kits and scanning them while making improvements in certain areas, that one can put all the possible different versions in a cluster of smaller tools which in a certain combination can eject version a, b, c, etc... which spreads the investment cost, while in the old days of annuals the prior year model was passe, thus erased, cus only the new model mattered and was paid for by the OEM.
